Blood Pressure Medication
Nervous System Inhibitors
Nervous system inhibitors relax the blood vessels by controlling nerve impulses. This causes the blood vessels to become wider and the blood pressure to go down.
Examples of nervous system inhibitors include:
Vasodilators directly dilate (widen) blood vessels by relaxing the muscle in the vessel walls. This causes blood pressure to go down.
Examples of this form of blood pressure medication include:
- Isosorbide mononitrate (Imdur®)
- Hydralazine (Apresoline®)
- Hydralazine and isosorbide dinitrate (BiDil®).
Treating high blood pressure can require considerable time and patience -- both for you and your doctor. It can be frustrating to take pills and possibly experience side effects, especially if you felt fine before beginning treatment. Remember that your blood pressure is only lowered while you are taking these medications. That's why medication for blood pressure can't be stopped in most cases, even after blood pressure is lowered. Some treatment must be continued over a lifetime.
Try not to get discouraged if you must be treated indefinitely. While some people can reduce their drug dosages after achieving normal blood pressure and maintaining it for a year or more, treatment usually can't be stopped entirely. Coping with the inconvenience of blood pressure medication is still much better than suffering a stroke or heart attack. Most people who are treated successfully usually live a long and healthy life.
